IMPORTANT:
Make-up air must be provided from a source
free of dry cleaning fumes. Make-up air that is
contaminated by dry cleaning fumes will result in irreparable
damage to the motors and other dryer components.
Exhaust ductwork should be designed and installed by a
competent technician. Improperly sized ductwork will create
excessive back pressure, which will result in slow drying,
increased use of energy, and shutdown of the burner by the
airflow (sail) switch, burner hi-limit or lint chamber hi-heat
protector thermostat. (Refer to the appropriate Installation
Manual for more details.)
CAUTION: Improperly sized or installed exhaust
ductwork can create a potential fire hazard.
Electrical and Gas Requirements
It is your responsibility to have all electrical connections made
by a properly licensed and competent electrician to assure that
the electrical installation is adequate and conforms to local and
state regulations or codes. In the absence of such codes, all
electrical connections, materials, and workmanship must
conform to the applicable requirements of the National Electrical
Code ANSI/NFPA NO. 70-LATEST EDITION or in Canada, the
Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or
LATEST EDITION.
IMPORTANT:
Failure to comply with these codes or
ordinances and/or the requirements stipulated in this
manual can result in personal injury or component failure.
The gas dryer installation must meet the American National
Standard...National Fuel Gas Code ANSI Z223.1-LATEST
EDITION, or in Canada, the Canadian Installation Codes CAN/
CGA-B149.1 M91 (Natural Gas) or CAN/CGA-B149.2-M91 (L.P.
Gas) or LATEST EDITION, as well as local codes and
ordinances and must be done by a qualified professional.
NOTE:
Undersized gas piping will result in ignition
problems, slow drying, and can create a safety hazard.
The dryer must be connected to the type of gas (natural or
L.P.) indicated on the dryer data label. If this information does
not agree with the type of gas available, contact the reseller
who sold the dryer or contact the factory.
The gas input ratings shown on the dryer data label are for
elevations up to 2,000 feet (609.6 meters), unless elevation
requirements of over 2,000 feet (609.6 meters) were specified
at the time the dryer order was placed with the factory. The
adjustment for dryers in the field for elevations over 2,000 feet
(609.6 meters) is made by changing the burner orifices. If this
adjustment is necessary, contact the reseller who sold the dryer
or contact the factory.
NOTE:
Any burner changes must be made by a qualified
technician.
Operational Service Check Procedure
Turn on electric power to the dryer.
To start dryer:
Display will read “Ready”.
Select a cycle using the keypad of the microprocessor controller
(computer).
The dryer will start, and the display will show cycle type and
minutes remaining.
Make a complete operational check of all the operating controls
to assure that the timing is correct, temperature selection
switches are functioning, etc.
Make a complete operational check of all safety-related circuits:
door switch(es), hi-limit thermostat, sail switch, cycling
thermostats, etc.
For gas dryers a gas pressure test should be taken at the gave
valve pressure tap of each dryer to assure that the water column
pressure is correct and consistent.
NOTE:
Water column pressure requirements (measured at
the pressure tap on the gas valve body):
Natural Gas _______ 3.0 in WC (6.9 mb)
L.P. Gas __________ 10.5 in WC (26.1 mb)
If computer program changes are required, refer to the Phase
7 Coin Operator’s Manual (ADC P/N 113912) for details.
The dryer should be operated through one complete cycle to
assure that no further adjustments are necessary and that all
components are functioning properly.
Description of Parts ___________________
Control Panel (Microprocessor)
Opening the control panel will allow access to the computer
board. The keypad inputs to the computer what temperature
and program has been selected. The computer controls the
entire operation of the dryer. It accepts inputs and gives outputs
to various parts throughout the dryer.
